SearchMash, the experimental site created by Google to improve the way search results are presented, introduced a new video search concept. If you search for "sunrise" or any other query, you'll see a list of thumbnails from the results. Hovering over a thumbnail, you can read the title of a video. Clicking on a search result, the video will open above the search results, along with a complete description. This way, you won't lose the results, and it's easier to see if a video is the right match.
